“I'm curious if anyone knows exactly how it worked between Terry Pratchett and Neil Gaiman. To me, the only parts that seemed more Neil Gaiman than Terry Pratchett were some of the (in my opinion) unnecessary language and occassional over-the-top violence. Much of the rest of it could've very easily been lifted straight out of a Discworld novel involving the apocolypse. This isn't to say I didn't like it, I love Pratchett, the writing style just seemed a bit one-sided to me and I wanted to know if anyone else noticed that.”
“I have a version of the book that includes an interview between the two asking this very question. Seems a lot of the beginning was Neil and then once they began calling and mailing each other pieces of the book back and forth the rest came up in sort of a blur till the end where Terry had more influence. They said something like... it was as though they spent most of the time trying to make each other laugh with the next piece. Hope that helps... ”
“If you read much of Gaiman's short fiction, you'll realize he has a very malleable literary voice that adapts to the style of whatever story he's telling. I agree that much of Good Omens felt like Pratchett to me, but I would suspect that's more a result of Gaiman blending to the writing style than of him not doing much of the work. ”
“I think i´ve read an interview with Gaiman saying he was busy with other thing (maybe Sandman) working with Good Omens so Pratchett had to do most of the writing.”
